# Batch Identify Person

> Resolve a bulk list of **emails** (business or personal) or `professional_network_profile_urls`
to the people behind them — reverse email lookup — as a single asynchronous job. This is the
only endpoint whose email resolution matches **personal** addresses (for example Gmail): the
synchronous `/person/enrich` and `/person/contact/enrich` reverse-look-up business emails only,
returning an empty `matches` array for a personal address.

<Note>
    An account may have at most 5 active (`pending` or `processing`) batch jobs at a time;
    submitting a sixth returns `429`.
</Note>

The job responds immediately with a `batch_id`. Poll `GET /batch/{batch_id}` (or provide a
`webhook_url`) and download the gzipped JSONL results file when the job completes. Each line is
one record `{matched_on, match_type, matches}` — the same match shape as the non-batch person
identify/enrich response, not wrapped in the enrich `{original_identifier, internal_id, data}`
envelope. `matches` holds the resolved person's `crustdata_person_id` and `basic_profile`. An
identifier that resolves to nobody returns an empty `matches` array and is not billed (compare
`entities_requested` with `entities_fulfilled`).




## OpenAPI

  title: Batch API
  version: '2025-11-01'
  description: >
    The Batch API is the asynchronous, high-volume alternative to the standard
    Company, Person, and Job endpoints.

    You submit a single job describing what you want, Crustdata processes it in
    the background, and you

    download the complete result set as a file. Batch jobs return the same data
    and the same record shapes

    as the corresponding non-batch endpoints — the difference is scale,
    delivery, and convenience.


    Every batch job follows the same three-step lifecycle:


    1. **Submit** — `POST` to a batch endpoint with your identifiers or query.
    The response returns
       immediately with a `batch_id`, an initial `status` of `pending`, and a `status_url`. No data is
       returned at submit time.
    2. **Poll** — `GET /batch/{batch_id}` until `status` reaches `completed` (or
    `failed`). Provide a
       `webhook_url` at submit time to receive a notification instead of polling.
    3. **Download** — completed jobs include a `download_url` (one merged
    results file) and `download_urls`
       (the same data split into parts). Files are gzipped JSONL — one record per line — and the links
       stay valid for 5 days.

    **Result-file record shapes**


    - **Enrich jobs** (database and live) wrap each record in an envelope:
      `{"original_identifier": ..., "internal_id": ..., "data": {...}}`. `original_identifier` echoes the
      exact value you submitted and `internal_id` is the resolved Crustdata ID, so you can join results
      back to your input list.
    - **Search jobs** (database and live) emit flat records identical to the
    corresponding non-batch
      endpoint's record shape — no envelope.

    **Limits and billing**


    - An account may have at most **5 active** (`pending` or `processing`) batch
    jobs at a time;
      submitting a sixth returns `429`.
    - The `x-api-version: 2025-11-01` header is required when submitting jobs.
    It is not required on the
      job status and list endpoints.
    - Billing is based on the number of records actually delivered in the
    results file
      (`entities_fulfilled`), not on how many you requested. Failed jobs are not charged.
